BOX-FASTENEB.

Specification of Letters Patent.

Patented Jan. 19, 1909.

Application filed June 29, 1908. Serial No. 441,006.

the following is a specification.

My invention relates to improvements in devices for locking and sealingthe cover retaining mechanism of shipping cases and it pertains to thatclass for which Letters Patent, No. 878,215, was issued to me February1, 1908.

By the device shown in such patent, the hasp is pivotally connected withthe cover and is adapted to engage laterally projecting lugs, which areri idly connected with. the walls of the case and said hasp is adapted,when in locking engagement with said projections, to be brought entirelybeneath a sealing plate by which access with the retaining hasp isprevented without breaking the seal, while by my present invention, thecover retaining hasp is pivotally connected with the walls of the case,and is adapted, when in locking position, to engage the upper surface ofthe cover retaining plate at one side instead of beneath the seal.

The construction of my invention is explained by reference to theaccompanying l the retaining members 18.

drawings in which-- Figure 1 represents a vertical section of one sideof the cover and case, together with the locking and sealing mechanism.Fig. 2 represents a bottom view of the seal removed from the case. Fig.3 represents a fastening plate removed from the cover as it is cutpreparatory to being bent into the required shape hereinafter described.Fig. 1 is a front View, part in section, of the cover retaining hasp.

Like parts are identified by the same reference figures throughout theseveral views.

1 is a cover which is provided with an aperture 2 for the reception ofthe cover retaining plate 3 and a seal 4. The plate 3 is secured to theinner side of the cover by a plurality of nails 5 and is provided with acentral aperture 6 for the reception of the seal. The cover retaininghasp comprises the laterally projecting and pivotally supporting arms 7,the vertical member 8, the respective sides of which are formedintegrally with said arms and the retaining loop 9, which is adaptedwhen in the locking position to engage the upper side of the plate 3.

The hasp is pivotally connected with the vertical walls 10 of the caseby the keeper 11 within the central recess 11. The keeper- 11 isconnected with the walls of the case by a plurality of nails or screws12. The plate 3 is provided upon one side with a vertical standard 13,which is formed integrally therewith and is bent upwardly, asSll()\\']lg0[ in Fig. 1, so as to engage the recess 1t formed in oneside of the seal.

The seal comprises the horizontal plate 15, provided with centralapertures 16 for the has been pivotally connected with the walls of thecase 10 by the keeper 11, as shown in Fig. 1, said seal being removed,the hasp is brought into lodging engagement with the plate 3, as shownin Fig. 1, when it is retained in such locked position by inserting theseal, as shown in Fig. 1, while said seal is retained in the aperture ofsaid plate 3 by It will be understood that preparatory to inserting theseal, the several retaining'n'iembers 18 are bent at an angle to thecircle described by said collar 17. whereby the outwardly projectinglugs 1%) of said retaining members 18 are adapted to engage beneath thelower side of the plate 3 and thereby prevent said seal from beingsurreptitiously withdrawn from the cover. \Vhen, however, it is desirousto remove the cover, said rctaining members 18 are broken anddis-engaged from the plate 3, whereby said plate is removed when theupper end of the hasp is dis-engaged from said fastening plate, wherebythe cover is released and may be opened and removed from the crate.

The plate 3 is provided with lugs 20, 20, 21 and 13. The lugs 20, 20 and21 are first cut with a punch or die, as shown in Fig. 3, when themembers 20, 20 and 21 are bent downwardly to the position shown in Fig.1, when they serve as a support to the lower side of the plate 3 beneaththe lug 9, where by the plate 3 at such point is reinforced andprevented from being bent downwardly reception of the removinginstrument andoor as it might otherwise be and the cover removed fromthe case. The lug 13 is adapted to be bent upwardly, as heretoforedescribed and shown in Fig. 1, whereby it prevents the seal from beingturned in its bearings.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is 1. In a device of the described class, thecombination of a shipping case, a hasp pivotally attached to the wall ofsaid case, a cover provided with an aperture for the reception of theprotruding end of said hasp, a cover retaining plate provided with anaperture of less diameter than the aperture of said cover, means forsecuring said retaining plate to said cover and a sealing plate adaptedto close the aperture of said cover retaining plate and to retain saidhasp in locking engagement with said cover retaining plate.

2. In a device of the described class, the combination of a shippingcase, a hasp com prising two parallel central members, the lower ends ofwhich are respectively folded back upon themselves and terminateoutwardly in opposite directions atright angles to said parallel centralmembers and adapted to serve as pivotal supports for the other membersof said hasp, the upper ends of said parallel members being providedwith a lug adapted to engage the cover retaining plate, means forpivotally attaching said hasp to the walls of the case, a cover providedwith an aperture for the reception of the protruding end of said hasp, acover retaining plate provided with an aperture of less diameter thanthe aperture of said cover, means for securing said retainingplate tosaid cover and means for retaining said hasp in locking engagement withsaid cover retaining plate.

3. In a device of the described class, the combination of a shippingcase, a hasp pivotally attached to the wall of said case, a coverprovided with an aperture for the reception of the protruding end ofsaid hasp, a cover retaining plate provided with an aperture of lessdiameter than the aperture of said cover, means for securing saidretaining plate to said cover, means for retaining said hasp in lookingengagement with said cover retaining plate, and a sealing platesupported from said cover retaining plate, provided with a plurality ofinwardly projecting resilient lugs, said lugs being adapted when saidsealing plate is in place, to engage the underside of said coverretaining plate and thereby prevent said sealing plate from beingremoved and said hasp from being thrown out of engagement with saidcover retaining plate.

4. In a device of the described class, the combination of a shippingcase, a hasp pivotally' attached to the wall of said case, a coverprovided with an aperture for the re ception of the protruding end ofsaid hasp, a cover retaining plate provided with an aperture of lessdiameter than the aperture of said cover, means for securing saidretaining plate to the inner surface of said cover, and a sealcomprising a horizontal seal plate, an annular collar formed at rightangles to said plate and a plurality of angular lugs connected at oneend with said seal plate and at their opposite ends with said annularcollar, said seal plate being provided with apertures for the receptionof a tool, by which said lugs may be broken, when desirous to remove theseal, all substantially as and for the purpose specified.

5. In a device of the described class, the combination of a shippingcase, a cover for said case, a locking device for securing said cover tosaid case, said cover being provided with an aperture above said lockingdevice, a fastening plate secured to said cover beneath said apertureand a seal for closing said aperture supported from said fastening plateabove said locking mechanism, said seal comprising a horizontal sealplate, an annular collar formed at right angles to said plate, aplurality of angular lugs respectively con nected at one end with saidhorizontal seal plate and at their opposite ends with said annularcollar, said lugs being adapted to engage the lower side of saidfastening plate and prevent said seal (without being broken) from beingremoved from said cover.

In testimony whereof I aifix my signature in the presence of twowitnesses.
